About this map

The Santa Lucia Range and the rugged Central Coast coastline dominate this 1948 survey, showcasing a landscape defined by significant military installations and remote mining operations. Large tracts are dedicated to the Hunter Liggett Military Reservation and Camp Roberts Military Reservation, reflecting the region's importance for training during and immediately after World War II. Near the coast, Camp San Luis Obispo sits just inland from Estero Bay.

Industry and education are marked by several remote sites, including the Klau Mine, Buena Vista Mine, and Union School. The Southern Pacific railroad serves as the primary transportation artery, connecting settlements like Paso Robles, Atascadero, and the county seat of San Luis Obispo. The topography transitions sharply from the coastal peaks of the Los Padres National Forest to the arid expanse of the Carrizo Plain and Antelope Valley to the east.
